Coriolopsis badia (Berk.) Murrill, Bull. Torrey Club 34: 466. 

 1907. 



Karafuto, Nakahara, 53. 



Coriolus abietinus (Dicks.) Quel. Ench. Fung. 175. 1886. 

 This species has been confused by some with Polystictus pellu- 

 cidus Berk. (Challenger No. 263), described from specimens 

 collected in Japan on slender stems of herbaceous plants. The 

 description of this latter species much resembles that of C. 

 abietinus, but the habitat as given is entirely impossible for it.
